$\frac{5}{2 x^{2}} + 7$

Step 1

To write $7$ as a fraction with a common denominator, multiply by $\frac{2 x^{2}}{2 x^{2}}$ .

$\frac{5}{2 x^{2}} + 7 \cdot \frac{2 x^{2}}{2 x^{2}}$

Step 2

Combine $7$ and $\frac{2 x^{2}}{2 x^{2}}$ .

$\frac{5}{2 x^{2}} + \frac{7 (2 x^{2})}{2 x^{2}}$

Step 3

Combine the numerators over the common denominator.

$\frac{5 + 7 (2 x^{2})}{2 x^{2}}$

Step 4

Multiply $7$ by $2$ .

$\frac{5 + 14 x^{2}}{2 x^{2}}$
